MEANS FOR ATTAGHING ROPES OR CABLES TO WINDING DRUMS.

Application filed December 30, 1921. Serial No. 525,929.

To all whom it may concern:

Be it known that I, ARTHUR GORDON FRENCH, a subject of the King of theUnited Kingdom of Great Britain and Ireland, and residing at Linotypeand Machinery l Vorks, Altrincham, in the county of Chester, England,have invented new and useful Improvements in Means for Attaching Ropesor Cables to Winding Drums, of which the following is a specification.

This invent-ion relates to improved means same rate, but it sometimeshappens that through expansion and contraction of the cable, the levelof the delivery board is dis turbed, which level, with the windingmechanism in ordinary use, can only with ditliculty be re-established.

According to the present invention this difliculty is eliminated by soattaching the cable to the winding drum as to enable it to be readilyadjusted circumferentially thereon. v

This invention will now be described with reference to the accompanyingdrawings in which Figure 1 is a side elevation, partly broken away, ofthe improved winding drum, showing the cable attached to the drum andalso broken away;

Figure 2 is a plan of Figure l, and

Figure 3 is a vertical section on the line 3-3 of Figure 1.

In carrying out the invention, the winding drum 1 is provided with theusual flanges 2 to prevent the cable 3 from slipping over the endsthereof, and with two peripheral openings 4, 5 (shown best in Figure 2),one of which, say 4, enables the cable 3 to be passed inwards from thewinding surface of the drum to a groove 6 formed in one side face ofsuch drum. This groove 6 extends around the said side face to a positionat which it reaches a passage 7 extending transversely through the drumand connecting with a similar groove 8 in the opposite side face, whichlatter groove connects with the peripheral opening 5, through which thecable again passes out on to the winding surface'of the drum, the cablewithin the passage forming what may be regarded as a bight.

The grooves 6, 8, in thetwo side faces are of relatively differentdepths, the groove 8 being less and the groove 6 greater than thediameter of the cable 3, which latter is retained in the grooves byannular rings 9, 10 secured to the respective sides of the drum byscrews 11 and bolts 12 respectively. By reason of the difference in thedepths of the grooves 6 and 8, the ring 9 attached to the side havingthe deeper groove 6 does not press on the cable 3, whereas the ring 10attached to the side having the shallower groove 8 presses on the cableand securely clamps it to the Winding drum.

With a drum constructed as before described, the cable can be readilyadjusted for levelling the pile delivery board by slacken ing the ring10 so as to release the cable 3,

which can then be pulled around the drum in either direction, and afterthe level has thus been restored or adjusted, this ring 10 is tightenedto again clamp the cable to the drum.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is i 1. The combination with a winding drum anda single cable adapted intermediate its ends to be coiled around it, ofa substantially annular groove formed directly in each side face of thedrum, openings in the periphery of the drum giving access to the cablefrom said periphery to the grooves, two rings adapted to partiallyenclose the grooves, and means securing one ring positively to each saidside face one for tightly clamping and the other for loosely retainingparts of the cable intermediate its ends in the respective groove.

2. The combination with a winding drum and a single cable adaptedintermediate its ends to be coiled around it, of a substantially annulargroove formed directly in each side face of the drum, openings in theperiphery of the drum giving access to the cable from said periphery tothe grooves, two rings adapted to partially enclose the grooves, oneadapted to bear on the cable and the other adapted to bear on the drum,

and means securing the rings to the respec tive side faces, one incontact with a part of the cable intermediate its ends for clamping ittightly within the respective groove and the other out of contacttherewith for retaining the cable loosely within the pertinent groove.

3. The combination with a winding drum and a single cable adaptedintermediate its ends to be coiled around it, of a substantially annulargroove formed directly in each side face of the drum, openings in theperiphery of the drum giving access to the cable from said periphery tothe grooves, two rings adapted to partially enclose the grooves, oneadapted to bear on a part of the cable intermediate its ends and theother adapted to bear on the drum, means securing the rings to theresoective side faces, one in contact with the cable for clamping ittightly within the respective groove, and the other out of contacttherewith for retaining the cable loosely within the pertinent groove,and a passage for the cable extending transversely through the drum formutually connecting together the two grooves' 4. The combination with awinding drum and a cable adapted to be coiled around it, a substantiallyannular groove in each side tace of the drum, two openings in theperiphery of the drum giving. access to the cable between said peripheryand the grooves and a passage for the cable extending transverselythrough the drum for mutually connecting together the two grooves, thecable entering this passage clockwise on one side of the drum andleaving it anticlockwise at the other side, so that said cable can meetand leave the periphery of the drum in the same direction and in thesame tangential plane.

5. The combination with a winding drum and a cable adapted to be coiledaround it, of a substantially annular groove formed directly in eachside face of the drum, openings in the periphery of the drum givingaccess to the cable inwards from the periphery to one of the grooves forone end of the cable and outwards from the second groove to theperiphery for the other end of the cable, a ring adapted to partiallyenclose one of the grooves, and means securing said ring positively tothe respective side face for tightly clamping in the groove of that facea portion of the cable intermediate its ends.

6. The combination with a winding drum and a cable adapted to be coiledaround it, of a substantially annular groove formed directly in eachside face of the drum, openings in the periphery of the drum givingaccess to the cable inwards from the pe riphery to one of the rooves forone end of the cable and outwards from the second groove to theperiphery for the other end of the cable, two rings each adapted topartially enclose one of the grooves, and means securing one ringpositively to each said side face, one for tightly clamping to the druma portion of the cable intermediate its ends, and the other for looselyretaining another such intermediate portion of the cable in therespective groove.

7. The combination with a winding drum and a cable adapted to be coiledaround it, of a substantially annular groove formed directly in eachside face of the drum, openings in the periphery of the drum givingccess to the cable inwards from the periphery to one of the grobves forone end of the cable and outwards from the second groove to theperiphery for the other end of the cable. a passage extendingtransversely through the drum mutually connecting together the twogrooves and within which the cable forms a bight intermediate its ends,two rings each adapted to partially enclose one of the grooves, andmeans securing one ring positively to each side face, respectively fortightly clamping and loosely retaining in the respective groove-s,portions of the cable at respectively opposite sides of the bight.

In testimony whereof I have aflixed my signature hereto.

ARTHUR GORDON FRENCH.
